Preparation
- Preheat your oven to 375°F (190°C) and prepare a 9x13-inch baking pan by greasing and lining it with parchment paper.
- In a large mixing bowl, combine the granulated sugar, sour cream, softened butter, and eggs, then beat until creamy.
- Gently fold in the mashed ripe bananas and vanilla extract until well combined.
- Sift together all-purpose flour, baking soda, and salt into the banana mixture; mix until just combined.
- Fold in the chopped walnuts, ensuring they're evenly distributed.
- Spread the brownie batter evenly into the prepared baking pan and bake for 30-35 minutes.
- Allow the brownies to cool in the pan for about 10 minutes.
- For the frosting, melt the butter until golden brown and nutty, then cool slightly and mix with powdered sugar and milk until smooth.
- Spread the frosting over the cooled brownies and slice into squares.

Notes
Use very ripe bananas for optimal sweetness; avoid overmixing to maintain a tender texture. Keep a close watch on the butter while browning to prevent burning.
